University Challenge is one of the world's top quiz shows, enjoyed by millions, both participants and observers. But Discworld fans may feel that not many questions cover the real questions in Life, for example, Who or what could be seen as the inspiration for the near-tragic accident from which nanny Ogg is saved only be a special willow-reinforced hat made for her by Mr Vernissage of Slice? And give a plausible origin for Mrs Rosie Palm, proprietor of the famous House of Negotiable Affection in the Shades. Each Faculty at the Unseen University has provided a set of questions, and answers are included for those who are not sure how the poisonous effects of quicksilver fumes are an occupational hazard of magic-users. The questions have been compiled by Mr David Langford, who knows quite as much - and arguably more - about the Discworld as its Creator, and Terry Pratchett has provided an Introduction.
